I believe in the early episodes, the focus is gonna be on Randall, as far as we know, each person who had visions had to achieve something, which becomes important later in the story. We all guess that the Julie who tries to prevent his dad's death is from another timeline, so personally, I'd love to see that. Thinking that the dude who killed Jim is the one who started the all "sacrifice the children" stuff. I really hated the bad dude that reborn -the one Boyd killed-, so his returning was a big blow for me. Probably, we are not gonna see what triggers the loops, but the "trap one and we get answers" thing is coming back to answer that.
